The Octane rest is not all it's cracked up to be. I tried it and thought that it was fine, but I didn't shoot it for very long (100 shots). However, we have had a few customers bring theirs back complaining that they wore out very quickly and wanted to get something else (Gander Mountain). I know that we are not the only shop that has had this problem. I'm not certain, but I think that Swamp Collie said that they have had to send back whole cases of them. On the other hand, I know at least five guys that I've shot with that use them and think they are great.
